Perhaps you should try some spelling variations:
yang ying » yang yang, yang jing, huang ying
heat gain » health gain, health gains, wheat grains
jeong ghi » hong ghi
ying lag » ying yang, ying loo
lag heat » large heat, a heat, lag test
yang jin » yang jun, shang jin, wang jing
ying jin » jing ji
yang jie » yang di, yang jui, yang xi
jeong mi » jeong _, jeong su, jeong 情

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: yang ying lag heat gain ((yang jin) OR (((ying jin) OR (yang jie)))) ((jeong ghi) OR (jeong mi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ying lag heat gain ((yang jin) or (((ying jin) OR (yang jie)))) ((jeong ghi) or (jeong mi)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang ying lag heat gain ((yang jin) or (((ying jin) OR (yang jie)))) ((jeong ghi) or (jeong mi)) ;*.
